Letters Patent No. 76,535, lated April 7, 1868.

IMPROVVEDAPPARATUS IOR GENERATING GAS.-

TO AILL WHOM IT MAY OONCERN:

Be it known that I, WILLIAM M. SLOAN, of Buffalo, in the county ofErie,'und State of New York, have invented a new and improved PortableGas-Generating Apparatus; and Ido hereby declare that the following isu. full, clear, and exact descriptionof the construction and operationof the same, reference being had to th annexed drawings, making a partof this speeiication, in which- The invention is represented by alongitudinal vertical section..

This invention consists, first, in providing within thecarburetting-chamber u. oatingfvessel having a felt bottom,for thepurposes hereinafterl shown, and, secondly, in heating steam or air thathasbeen carburetted, and thereby fixing it as a gas.' Y l In thedrawings, A represents the catrburetting-chanher supplied with a currentof steam or atmospheric nir through a pipe, B, the part of which outsideofthe chamher'A may be made of exible or inflexible hose or gas-tube,and the portion of which, B', inside of the chamber, is to beconstructed of fiexiblc tubing.

I C represents the curburctting-iuid or substance used in the chamber A.`D isvahollow vessel or Hout resting on the liquid, C, and filled nt'thetop with air'or steam' from the pipevB. Its bot-torn, D, consists of apiece'of felt stretched tightly acrossand confined to the lower 'edgcsof the sido walls.- E is a pipe leading from the upper part of lthechamber A to a hollow drum or vessel, F, sit-uatedover or near afire-chamber, I, of a heater, H.' The steam or air, having heen forcedthrough pipe B into vessel D, and escaping through every part of itsfelt bottom Dinto the. carburettiiig-luid, and thence rising in bubblesto the upper portion of' -the chamber A, passes over through pipe E todrum F, where it is heated by moans of a fire burning in fire-chamber Iof the heater. Having thus been heated and partially fixed, thegas-passes from drum F through pipe Ki into th'o rst of a series ofupright cylinders L L"L.Ll arranged in a vertical position around thelire-pot I. Entering'at thc top of one or" these cylindersit passes downthrough it, and escapes at its bottom through a. short pipe'or passage,l, into the bottoni of the 'adjoining cylinder L', throughwhich itrises, escaping in turn through the'pnssage Zinto the-top of the nextadjoining cylinder L, then-ce downfand into the .next, 82e., Ste.,passing in this manner nround the tire-pot, and finally escaping fromthe apparatus at the bottom 'or top of the cylinder L, the last ot' theseries, when, zii'ter being passed through'ia cooling-apparatus, it isready for use.

The object in passing-thc gas through the cylinders around the fire-'potis to heult it to a higher degree than .it `was when it escaped from thedrum F. The arrangement of the cylinders, fire-pot, and drum F, as shownin the drawings, utilizes the heat of the heater to the highest degree.From the mom-cnt ofl entering thchcater till it nally escapes from it,through all its long passage, the gas is' constantly exposed to a largeheated surface, which, in the course of its passage, reaches every partofit, and thoroughly heats it, changing or destroying particles offoreign matter-in it, and giving the whole the character' of apermanentlydixed illuminating-gas.-

Insteud of felt, aiiy thick, porous cloth, which will operate inanequivalent manner, may be employed for the' bottom of float D. Andinstead of arranging the retorts or cylinders L L1 L2, 86u., verticallyin a circle around the grate, as shown, they muy be arrangedhorizontally, forming an arch over the tire, if preferred, any otherposition that will enable the heat to act upon them all to the greatestadvantage.

Having thus described my invention', what I 'claim as nexrpand desire toSecure by Letters Patent, is- YJ'he combination of thecarbwetting-apparatus A B D, when constructed and operating nsdescribed, with the ire-chamber I, cylindrical retorts L'L L2,`dtc.,iand pipe E, when'the parts lust mentioned are arranged in themanner set forth, the whole operating together.substantially as and forthe purpose specified.
